It looks like pulp is having problems connecting to qpid:

I'm pretty sure that this is the culprit here: https://git.io/vDABe. From my testing it looks like localhost resolves to ::1 before those lines get called:

$ telnet localhost 5671
Trying ::1...
Connected to localhost.
Escape character is '^]'.

Then after:

$ telnet localhost 5671
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

I tried testing this out by removing this line from /etc/hosts on the box after it came up but before the BATS tests get run:

::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

After that, I the BATS tests passed (three out of three times I tested) which seems to confirm my suspicion. I think Pulp is connected or trying to connect to qpid via ::1 as ipv6 gets disabled.

I see three possible solutions:

1. Restart pulp after disabling ipv6 in BATS
2. Have ansible or BATS update /etc/hosts to remove the ::1 line
3. Configure pulp to point to qpid at 127.0.0.1 instead of localhost

Option 1 may not work as long as localhost could resolve to ::1. Option 3 is a little hard because the certs point to localhost.

Regardless though, I think this is probably a Katello bug. We could maybe make it clearer in the pulp logs when it can't connect to qpid but not sure how helpful that would be over a "Network unreachable" error like we do now.
